I have to say my favorite comes from a song called "Rats in my Bedroom:"

"Everyone says that the big bugs're down south, but I saw a roach cross my table, and it had a ham-hock in its mouth!"

Just the visual is worth it....!

In a close second must be BB King:
"I bought you a ten dollar dinner, an' you said thanks for the snack.
I bought you a brand new Ford, but you said I want a cadillac. I gave you seven children, and now you want to give them back. I been downhearted, baby, ever since the day we met."
